Before you run the statement you could try
STRDBG UPDPROD(*YES)
STRDBG UPDPROD(*YES)
RUNSQL SQL('delete from rob/fb where column1=''C''') COMMIT(*NONE)
...
1 rows deleted from FB in ROB.
Message ID . . . . . . : SQL7955
Message type . . . . . : Completion
...
ENDDBG
I believe there are sql variables in embedded sql which will tell you
this.
